When further heated, the anhydrous material decomposes into sulfur dioxide and sulfur trioxide, leaving a reddish-brown iron(III) oxide. Thermolysis of iron(II) sulfate begins at about 680 °C (1,256 °F). 2 FeSO 4 Fe 2 O 3 + SO 2 + SO 3. Like other iron(II) salts, iron(II) sulfate is a reducing agent.
Iron sulfide or Iron sulphide can refer to range of chemical compounds composed of iron and sulfur. Minerals
Iron(II) sulfide or ferrous sulfide (Br.E. sulphide) is one of a family of chemical compounds and minerals with the approximate formula Fe S. Iron sulfides are often iron-deficient non-stoichiometric .
Equal masses of iron (Fe) and sulfur (S) react to form iron sulfide (FeS), but because of its higher atomic weight, iron is the limiting reagent and once all the iron is consumed some sulfur remains unreacted

Milk of sulfur (lac sulphuris) – formed by adding an acid to thion hudor (lime sulfur). Natron/soda ash/soda – sodium carbonate. Na 2 CO 3; Nitrum flammans – ammonium nitrate. Sugar of lead – lead(II) acetate, formed by dissolving lead oxide in vinegar. Thion hudor – lime sulfur, formed by boiling flowers of sulfur with slaked lime.
Carfentanil, an altered version of fentanyl that is said to be 100 times more potent, the CDC warned in a Dec. 5 alert. ... "Even a tiny amount can increase the potency of a drug mixture, leading ...
Iron shows the characteristic chemical properties of the transition metals, namely the ability to form variable oxidation states differing by steps of one and a very large coordination and organometallic chemistry: indeed, it was the discovery of an iron compound, ferrocene, that revolutionalized the latter field in the 1950s.
